Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 238.15 g/mol gives 1,3-dichloro-5-methoxy-isoquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,3-dichloro-5-methoxy-isoquinoline (CAS 24623-38-9), molecular formula C10H17Cl2NO and molecular weight 238.15 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,3-dichloro-5-methoxy-isoquinoline (C10H17Cl2NO) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 238.15 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
